General introduction Gram-negative, obligate intracellular coccobacilli bacteria that infect mammals and arthropods Rickettsiae are transmitted in the arthropods, which serves as both vector and reservior Both dna and rna Is sensitive to antibiotic

MYCOBACTERIUM THIS GENUS IS COMPOSED OF. Strictly aerobic, acid-fast rods, does not Stain well (gram stain indeterminant) DNA has high g+c content, unique cell wall, Mycolic acid carbon chain length c60 Relatively slow growth(two groups) A. RAPID GROWERS (Visible colonies in <5 days B SLOW GROWERS (Visible colonies in 5 days)

Biological Features Aerobic, Gram, noncapsulated, rods Gray-black colonies on tellurite亚碲酸盐 medium o Metachromatic granules Chinese-letter morphology in Gram stain

Actinomyces Israelii Anaeslundii a Gram positive sulfur granule; Related to decay tooth and peridentitis

Category Spore- forming: rod, Gram(+)--Clostridium Nonspore- forming: see next slides

Vibrio sp Gram-negative rods Curves or comma shaped Non-spore forming Highly motile-single polar flagella Associated with salt water Oxidase positive
